ANGULAR-DISTRIBUTION OF N-2 KVV AUGER ELECTRONS INDUCED BY 1.5 AND 2 MEV PROTONS

The angular distributions of the KVV Auger spectra of N-2 molecules in duced by 1.5 and 2 MeV proton impact have been studied at 13 different angles from 0 degrees to 180 degrees relative to the ion beam. Beside s the transition energies, line widths (FWHM) and relative intensities , the anisotropy parameters and the anisotropy coefficients of the Aug er lines have also been determined. Strong indications have been found that the K-shell ionization cross section in homonuclear molecules ma y depend on the orientation of the molecular axis relative to the ion- beam direction.
